How can I extract information on the reconstructed density matrix?

[silvio-sjsj]

Following this tutorial: Density matrix reconstruction. After the fit method and the plots with the metrics (KL-divergence and Fidelity) how can I extract the reconstructed density matrix so I can compare with the real density matrix?

I like to achieve something like this:

where the image on the left is the true density matrix, under true_matrix variable (matrix_path_real = "N2_W_state_target_real.txt" and matrix_path_imag = "N2_W_state_target_imag.txt") and the image to the right is the reconstructed matrix. How can I extract the information on the reconstructed matrix? Where is it stored?
